Washington Commanders right tackle Sam Cosmi underwent thumb surgery Tuesday, a source with knowledge of the situation confirmed — marking the latest blow to a dinged-up offensive line.
It’s unclear how long Cosmi will be out with the injury. But if he is indeed unavailable for Sunday’s game against the Tennessee Titans, he’ll be the team’s third starting linemen to be sidelined with an injury. Starting center Chase Roullier (knee) and guard/center Wes Schweitzer (concussion) have landed on injured reserve.
In Sunday’s loss to the Dallas Cowboys, the Commanders also benched veteran Trai Turner at right guard for Saahdiq Charles.
The Commanders line has struggled mightily this season as quarterback Carson Wentz has been sacked a league-high 17 times. Washington’s line ranked as one of the best blocking units in the league last year, but the team lost starting guards Brandon Scherff and Ereck Flowers in the offseason.
Veteran Cornelius Lucas figures to replace Cosmi, a 2021 second-rounder out of Texas, at tackle.
Lucas started seven games for Washington in 2021. Over his three seasons with the franchise, the 31-year-old has become a valuable swing tackle — playing on the left side in 2020 and then the right last season. The Commanders re-signed Lucas to a two-year, $8.2 million contract in March.
